# Cloud Migration [Cloud Migration](https://iits-consulting.de/en/services/cloud-devops/cloud-migration) ## Cloud Migration We rebuilt and migrated a BSI C5-compliant hospital platform in months after another provider spent over a year on it. For Telekom, we cut infrastructure cost by 50 % at 99.98 % availability.Your migration starts with an inventory and ends with a platform your team runs or we do.

Not moving servers from A to B. Anyone can do that and end up with the same problems on a more expensive bill. A real migration is a set of decisions: what moves as it is, what gets modernised, what stays on-prem for good reason. And it means sorting out security, compliance and monitoring *before* production traffic moves, not after the first incident. At iits, cloud architecture, software engineering and CloudOps sit in one team. So you don't just arrive in the cloud. You arrive able to run it. ### Sovereign cloud or hyperscaler? Both, if it makes sense. We're a long-standing T Cloud Public partner and build on STACKIT, AWS, Azure and GCP. So the platform question gets answered by your data, your regulator and your budget, not by whoever we happen to resell. ### Modernise where it pays, move where it doesn't Not every workload deserves a rewrite. We decide per application whether it's rehosted, replatformed or refactored, based on business value, dependencies and what it costs to run afterwards. You get a portfolio decision you can defend to finance. ### Day-two operations, built in from day one A migration is done when your team can run the platform. Landing zone as code, GitOps deployments, monitoring and backup live before traffic moves. Runbooks and dashboards included or our CloudOps team keeps operating it for you. ## Why this survives the cut over We migrate the systems others won't touch. KRITIS, healthcare, petabyte-scale data on sovereign cloud or hyperscaler, whichever the regulator and the workload demand. ### Built for regulated and critical workloads KRITIS, hospitals, utilities, carriers. BSI C5 controls and GDPR requirements designed into the platform, with audit evidence available from day one. ### Platform choice follows workload and regulation T Cloud Public or STACKIT when the regulator says so, AWS, GCP or Azure when the workload does. Leading T Cloud partner, direct line to T-Systems. ### Petabytes, not pilots Production data at petabyte scale, with transfer plans and cut-over windows that hold. ### 55 Terraform modules, 40 Helm charts Every landing zone from a tested library, deployed via GitOps. Built from tested, reusable modules rather than one-off infrastructure. ### We stay after go-live, if you want KumoOps: fixed monthly price, incident response under 15 minutes, live chat instead of tickets.

The business case before the first ticket. Step 01 ### Build the foundation once Landing zone from our Terraform and Helm library: network, identity, encryption, guardrails. BSI C5 and GDPR designed in. Step 02 ### Move in waves, rehearse every one Low-risk first. Each wave has a dry run, a rollback path and a downtime window you knew about in advance. Step 03 ### Go live, hit the numbers, hand over We stay until availability and cost meet the targets from step one. Then your team runs it, with runbooks or we do. Step 04 ## Moving to T Cloud Public? We’re a long-standing T Cloud Public partner. When it’s the right platform for your workloads, there’s a cheaper way to book it.

After iits took over management of our project in December 2022, we saw a remarkable improvement in the performance and efficiency of our systems. The seamless transition under the same terms as our previous IT service provider, combined with ongoing optimizations, has not only reduced our costs by 50% but also increased the availability of our applications to over 99.98%. Stefan Marienfeld Head of Solution Management Deutsche Telekom AG ## What we build with. Proven modules, not a blank Terraform file. 55+ modules, 40+ Helm charts, built with a solid platform engineering mindset. CLOUD PLATFORMS - T Cloud Public - STACKIT - AWS - Azure - GCP INFRASTRUCTURE & DELIVERY - Terraform - OpenTofu - Kubernetes - Helm - GitLab - Argo CD - CI/CD - Flux CD SECURITY & IDENTITY - Keycloak - Vault - Cert-Manager - Kyverno ## That humming noise in the basement? We can fix it. Send a non-binding project inquiry and find out what it would take to move it, what it would cost to run, and whether it's worth it at all.
